3-Stage Gear Motor (2 UDL 2.2kW And 1 NMRV 75)

The 3-Stage Gear Motor (2 UDL 2.2kW And 1 NMRV 75) is a gear motor assembled from an electric motor-specifically a 3-phase electric motor-combined with a gearbox-specifically a 3-stage gearbox. This combination creates a drive assembly capable of stepless speed adjustment, deep speed reduction, and high torque generation, perfectly meeting production lines requiring flexible speed variations and strong pulling force.

General design of the 3-Stage Gear Motor (2 UDL 2.2kW And 1 NMRV 75)

The 3-Stage Gear Motor (2 UDL 2.2kW And 1 NMRV 75) features a drive assembly housed in a sturdy cast aluminum/cast iron frame, ensuring rigidity and reducing vibration during operation. The components are connected by standard flanges, making installation convenient and precise. The gearbox output shaft is designed with a standard NMRV square shape, easily connecting with pulleys, couplings, or gears. The overall device is compact, streamlined, and optimizes space in production lines.

Detailed structure of the 3-stage gear motor (2 UDL and 1 NMRV)

The 3-Stage Gear Motor (2 UDL 2.2kW And 1 NMRV 75) belongs to the category of gear motors from 1.1kW to 3.7kW, formed by a 3-phase electric motor 2.2kW 3Hp combined with a 3-stage gearbox (2 UDL 2.2kW and 1 NMRV 75), creating a multi-stage drive assembly that operates stably and flexibly.

Electric motor structure:

• Copper wire stator: Creates a strong rotating magnetic field, maintaining stable performance during continuous operation.
• Squirrel-cage rotor: Sturdy structure, reduces vibration, transmits torque smoothly.
• Cast iron or cast aluminum housing: Protects internal parts and provides good heat dissipation.
• Shaft – bearing – cooling fan: Helps the shaft rotate smoothly, reduces friction, and supports cooling.

Gearbox structure:

• Stage 1 is a mechanical speed variator (UDL)-specifically a 2.2kW 3Hp motor speed controller-adjusting the friction radius to continuously create different output speeds.
• Stage 2 is a 2-stage gearbox-specifically the UDL 2.2kW – NMRV 75 2-stage gearbox-creating a large gear ratio and high torque with smooth operation.
• Manual speed control mechanism: A dial or handwheel allows speed changes even while the equipment is running.
• Body housing + bearing supports: Monolithic structure stabilizes the system and protects the variable speed assembly from dust, vibration, and impact.

How to install an electric motor with 2 UDL units and 1 NMRV worm gearbox to form a 3-stage gear motor

Thành Thái Motor guides the assembly of the 3-Stage Gear Motor (2 UDL 2.2kW And 1 NMRV 75) system (combining an electric motor, 2 UDL mechanical speed variator units, and 1 NMRV worm gearbox):

• Step 1: Connect the electric motor to the first UDL speed variator unit
  • Place the equipment on a flat and sturdy surface.
  • Align the shaft of the electric motor so that it is completely concentric with the mounting hole (input) of the first UDL unit. Push the engagement firmly into the flange face and tighten all bolts evenly to secure it tightly.
• Step 2: Install the second UDL unit (Creating a dual speed variator assembly)
  • Continue connecting the output shaft of the first UDL unit to the input of the second UDL unit.
  • Bolt and tighten the flange between the two speed variators. Splicing these 2 UDL units in series helps expand the speed adjustment range, allowing the system to change revolutions flexibly and much slower than using a single UDL.
• Step 3: Attach the speed variator assembly to the NMRV gearbox
  • Lift the completed assembly (Motor + 2 UDL) and fit the output shaft of the second UDL into the hollow shaft of the NMRV gearbox.
  • Pay attention to accurately aligning the keyway so that the engagement goes deep and concentric, avoiding shaft jamming or key breakage during operation. After the flange is tight, use a wrench to tighten all connecting bolts.
• Step 4: Overall inspection
  • Review along the system from the motor head to the end of the NMRV gearbox, ensuring 100% of the bolts at all 3 connection points are locked tightly.

The characteristic right-angle output shaft design of the NMRV series on the 3-Stage Gear Motor (2 UDL 2.2kW And 1 NMRV 75) completely resolves the problem of machinery layout in cramped workshop spaces. The load-bearing axial roller bearings combined with high-grade rubber oil seals keep the oil chamber tightly sealed, completely preventing oil leakage and dust penetration in environments with many impurities.
